In NYC, 49 pregnant women had Zika, 1 baby born with defect

Officials say 49 pregnant women have tested positive for Zika in New York City since April, and one baby has been born with microcephaly due to the mosquito-borne virus.

Overall, more than 3,400 at-risk pregnant women have been tested under the city's Zika action plan.

Officials say most people who tested positive in the nation's largest city were infected while traveling to Zika-affected areas, with a small minority getting it via sexual transmission.

Mayor Bill de Blasio said Tuesday that the city has committed $21 million to protect New Yorkers from Zika. He and other politicians, including fellow Democrat U.S. Rep. Carolyn Maloney, called on Congress to approve $1.9 billion in emergency funding.

Federal health officials say there have been 420 Zika cases in New York City.
